Randomized Controlled Trial Multicenter Study
Early Intervention with epoetin alfa during platinum-based chemotherapy: an analysis of quality-of-life results of a multicenter, randomized, controlled trial compared with population normative data.
To evaluate the effect of epoetin alfa on quality of life (QOL) in patients with solid tumors and mild-to-moderate anemia receiving platinum-based chemotherapy relative to population norms. ⋯ Patients in this study had impaired QOL compared with population norms. Early treatment with epoetin alfa to correct anemia improved QOL in a statistically significant and clinically meaningful way, and improvements were greater in patients with baseline Hb levels >10.5 g/dl.

Randomized Controlled Trial Multicenter Study
Early intervention with epoetin alfa during platinum-based chemotherapy: an analysis of the results of a multicenter, randomized, controlled trial based on initial hemoglobin level.
This analysis of the results of a randomized, controlled trial evaluating the effects of epoetin alfa (EPO) therapy on transfusion requirements, hemoglobin (Hb), and quality of life (QOL) in patients with cancer receiving platinum-based chemotherapy was conducted to evaluate the effect of initial Hb level on study outcomes. ⋯ In patients with cancer receiving platinum-based chemotherapy and with baseline Hb levels >10.5 g/dl, early intervention with EPO reduces transfusions, maintains Hb level, and maintains or improves QOL. This study supports the positive effects of early intervention when analyzed according to initial Hb value.

Randomized Controlled Trial
Paclitaxel/carboplatin/etoposide versus paclitaxel/topotecan for extensive-stage small cell lung cancer: a Minnie Pearl Cancer Research Network randomized, prospective phase II trial.
To compare the combination of paclitaxel (Taxol; Bristol-Myers Squibb, Princeton, NJ, http://www.bms.com) and topotecan (Hycamtin; Glaxo SmithKline, Philadelphia, http://www.gsk.com) with paclitaxel, carboplatin (Paraplatin; Bristol-Myers Squibb), and etoposide (Etopophos, VePesid; Bristol-Myers Squibb) in patients with previously untreated extensive-stage small cell lung cancer. ⋯ The paclitaxel-carboplatin-etoposide combination produced a superior overall response rate and time to progression in patients with extensive-stage small cell lung cancer compared with paclitaxel plus topotecan. The platinum compounds continue to be a necessary component of the initial therapy for these patients.

Randomized Controlled Trial Multicenter Study
Randomized comparison of epoetin alfa (40,000 U weekly) and darbepoetin alfa (200 microg every 2 weeks) in anemic patients with cancer receiving chemotherapy.
This is the first randomized, open-label, multicenter trial designed and powered to directly compare the hemoglobin (Hb) response to epoetin alfa (EPO), 40,000 U once weekly (QW), with that to darbepoetin alfa (DARB), 200 microg every 2 weeks (Q2W), in anemic patients with cancer receiving chemotherapy (CT). Transfusion requirements, quality of life (QOL), and safety also were evaluated. Adults with solid tumors scheduled to receive CT for > or =12 weeks and with baseline Hb < or =11 g/dl were randomized to receive either EPO 40,000 U QW (n = 178) or DARB 200 microg Q2W (n = 180) s.c. for up to 16 weeks. ⋯ The mean increase in Hb from baseline was significantly higher at weeks 5, 9, 13, and the end of the study with EPO than with DARB. The number of units transfused per patient was significantly lower for the EPO group than for the DARB group. The proportions of patients requiring transfusions, mean QOL improvements, and tolerability profiles were similar in the two groups.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Efficacy of first-line letrozole versus tamoxifen as a function of age in postmenopausal women with advanced breast cancer.
To compare the efficacy, in regard to time to progression (TTP) and objective response rate (ORR), of letrozole (Femara; Novartis Pharma AG; Basel Switzerland), an oral aromatase inhibitor, with that of tamoxifen (Tamofen; Leiras OY; Turku, Finland) as first-line therapy in younger (<70 years) and older (>/=70 years) postmenopausal women with advanced breast cancer. ⋯ The data show that letrozole, 2.5 mg once daily, is as effective in older, postmenopausal women as it is in younger postmenopausal women with advanced breast cancer. In addition, letrozole was more effective than tamoxifen in both younger and older patients.
